⛓ How to join two arrays in JavaScript

const one = [`aaa`, `bbb`, `ccc`]
const two = [`ddd`, `eee`, `fff`]
Enter fullscreen mode Exit fullscreen mode

You have the above arrays.
How will you merge those into a single array?

You can use concat method.
This method will work in older browsers also.

const megaArray = one.concat(two)
Enter fullscreen mode Exit fullscreen mode

There is a new way to do this.
You can use the spread operator in JavaScript.

const megaArray = [...one, ...two]
Enter fullscreen mode Exit fullscreen mode

Much cleaner!

That's fine, you can still create an account and turn on features like 🌚 dark mode.
